Answer:
Number of blue marbles is 24
Step-by-step explanation:
For pink marbles
45÷100×120=54
For green marbles
35÷100×120=42
Let number of blue marbles=x
x+42+54=120
x+96=120
x=120-96
x=24
1L = 1,000ml
Therefore
2.486L = 2.486 · 1,000ml = 2,486ml
<h3>Answer: 2.486 L = 2,486 ml</h3>
She invested "a" at 4% and "b" at 7%
now, how much is 4% of a? well 4/100 * a or 0.04a
how much is 7% of b? well 7/100 * b, or 0.07b
now, we know their interest yield was 480, thus
0.04a + 0.07b = 480
we also know, she had 8000 to invest and split it in two investments, so
a + b = 8000
now
solve for "a" to see how much she invested at 4%
what about "b"? well b = 8000 - a
Let the number of hats they sold be x and the number of t shirts they sold be 23-x.
12x + 10(23-x) = 246
x = 8
The number of hats they sold is 8.
23-8= 15
The number of t shirts they sold is 15.
